8. Common questions about the web server Plug-in
In the web server Plug-in, what do the following options mean and what are the recommended settings for these options? LoadBalanceWeight; MaxConnections; ConnectTimeout; ServerIOTimeout
What affect does Session Affinity have?
How are connections handled during Plug-in Fail-over?
Are more than one instance of the plugin loaded by the web server? If so, do the plugin instances share information with each other?

9. Configuring the WebSphere Application Server Web server plug-in for multiple Web sites
Internet Information Services 6.0 (IIS), which ships with Microsoft Windows 2003, allows multiple Web sites to be run within a single IIS server. Given this ability, can the WebSphere Application Server Web server plug-in be used with multiple IIS Web sites?

10. PK90452: Session affinity fails when using URL rewrite and HTTP plug-in
Session affinity using URL rewrite fails when plug-in fails to correctly extract cloneID from the URL.

11. Tuning IBM HTTP Server to maximize the number of client connections to WebSphere Application Server
Out of the box, IBM HTTP Server supports a maximum of 600 concurrent connections. Performance will suffer if load dictates more concurrent connections, as incoming requests will be queued up by the host operating system. You can increase the number of maximum connections allowed by IBM HTTP Server by editing the httpd.conf file.

12. Intermittent delay returning response to a client request when ServerIOTimeout is set to non-zero value
When customer uses a non-zero value for the ServerIOTimeout option, responses to client requests are intermittently taking an excessive amout of time to be returned to the client. In fact the responses are being returned when the ServerIOTimeout value pops.
